Reliable Single Phase Active Energy Electric LoRaWAN Meter with LCD Display

 

Description:

DDS155 series BR (LoRaWAN) single phase electric meter is a kind of fully digitized energy meter which adopts the SOC high-density V9821S chip.

 

Besides measure active energy, it also has function for online power display, smart anti-tamper, overload control, remote meter reading and etc.

 

It sends data to corresponding gateway through LoRaWAN wireless network. It has advantages in high accuracy, low power consumption, and good stability that can be widely used for the single phase alternating current in city, rural areas or factory enterprises, etc.

 

Feature:

  • Normal working temperature: -25℃~ +55℃
    Limited working temperature: -45℃~ +70℃
    Relative humidity: ≦85%
  • Overall dimensions: 154mm×110mm×60mm
  • Product material: ABS
  • Support for LoRaWAN communication, RS485

Main function characteristics:
(1) Adopt SOC singlechip V9821S, enhanced 8052MCU core, energy measurement, integrated
analog front end, RTC module, LCD driver, Flash, accurate measurement and active energy display. (2) Remote ON/OFF control: according to power usage, can send power off command from main
station, cut off user’s load circuit. Or send power on command to connect user’s load circuit. (3) With LoRaWAN wireless network to transmit data to corresponding gateway, automatically
upload data, default 10 mins as period to upload data (this period can be set ). (4) Compatible with communication protocol DL/T645-2007. 2.

6) Main and auxiliary terminal connection
Main terminal connection follows Figure 2, 1 as L In, 2 as L Out, 3 as N In, 4 as N Out. There are 4 auxiliary terminals on the top of main terminal, in which 7 & 8 as measure pulse output.

 

LoRaWAN communication interface:
Using LoRaWAN communication for meter reading and parameter setting. When meter reading, remote meter data transmission software provided by our company can be used for meter reading and parameter setting. It is also possible to design a software and hardware system that fully complies with the protocol requirements for meter reading and parameter setting according to the power industry standard DL/T 645-2007 (supporting part of the communication protocol).

Please take attention to the following points when handle meter reading and parameter setting:
a. Parameter setting, please just setting items which refers to the certain meter.

b. LoRaWAN active upload data format:
